Trust me on this. Make an account (you'll need it) and with a password you've never used before. PM me the username and pass. I'll make it 50gb for you. The 50gb thing only works or a kind of 'coworkers' promotion thing offered by box. I know it sounds like i'm gonna steal the account, but you can make an account with one of those minute emails and a fake password, but it won't be of much use to you(minute email's inboxes empty themselves after a while).
